Keep a copy of your passport digitally scanned onto a secure biometric USB Flash Drive.

Your photos can be copied onto these tiny little drives for safe storage.

Bring your emails and important trip itinerary with you.

There was a time when USB keys—aka thumb drives, flash tokens, or keychain drives—were simple storage devices that helped you carry a file or two. The size was cool, but they weren't really much better than a high-tech floppy disk. 

Our new generation of "smart" flash drives deliver entire applications on a single USB key. Plug a USB key into any system and you can use your browser, e-mail client, and applications as if they were loaded on that system. Unplug it, and there is no trace of you or your software on the system
